Abstract:

Abstract： According to rock physical and mechanical properties and hydro geological conditions, adopting pre-drainage project, the project lowers water level and water pressure of aquifer in advance, and avoids mining operation stagnation caused by water inflow in stope, which effectively reduces the effect of aquifer on slope stability and Water pressure of aquifer.
